Woodworkers in the furniture industry are exposed to wood dust in their workplaces. The aim of this study is to investigate the effect of occupational wood dust exposure on the nasal mucociliary transport rates (NMTRs) in woodworkers. Twenty five woodworkers and 30 healthy controls were included in this study. Wood dust concentration in workplaces was measured using the sampling device. (99m) T...

The objective of this work was to study Cr(VI) sorption/desorption on two by-products from the wood industry: pine sawdust and oak wood ash. The retention/release experiments were carried out using standard batch-type trials. In the sorption-phase experiments, pine sawdust showed 23% sorption when a concentration of 100 mg Cr(VI)ŸL-1 was added, whereas sorption on oak wood ash was 17%. In the d...

Tracking&Tracing-systems have been used for years in the logistics and food industry for the monitoring, control and management of processes. In general, the usage of systems includes applications such as finding the source of recalls, proof of product quality and origin, improving logistics and production processes. The benefits of these systems in the specific environment of the wood supply c...

Primary wood manufacturing is one of the key sectors in Canada’s wood industry. The sector has gone through significant changes during the last decade. These changes were caused by a variety of factors, such as technological advancement, market restructuring, and policy and regulation shifts. One of the most affected provincial sectors due to these circumstances was the primary wood products in...

CCA has been banned for residential use as a wood preservative in North America by the end of 2003. The alternatives will be copper-based chemicals, such as Ammonium Copper Quat (ACQ) or Copper Azole (CA). Leaching of copper from treated wood to environment will become one of the most important issues for the wood preserving industry. So far, no wood treatment with the new copper alternatives o...

The white-rot fungus, Physisporinus vitreus, degrades the membranes of bordered pits in tracheids and consequently increases the permeability of wood, which is a process that can be used by the wood industry to improve the uptake of wood preservatives and environmentally benign wood modification substances to enhance the use and sustainability of native conifer wood species. To understand and a...

fast pyrolysis is an attractive technology for biomass conversion, from which bio-oil is the preferred product with a great potential for use in industry and transport. corn wastes (cob and stover) and eucalyptus wood are widely being produced throughout the world. in this study, fast pyrolysis of these two materials were examined under the temperature of 500 °c; career gas flow rate of 660 l h...

In the forest products manufacturing industry, recent price increases in the cost of high-quality lumber together with the reduced availability of this resource have forced manufacturers to utilize lower grade hardwood lumber in their manufacturing operations. This use of low quality lumber means that the labor involved in converting this lumber to usable parts is also increased because it take...
